Answer:
The length is 15 and the width is 5
Step-by-step explanation:
Let the breadth be x cm then its length be 3x.
Perimeter of the rectangle = 2 (x+3x)
40=2(x+3x)
40=8x
x=5
breadth = 5
length = (5×3) = 15
w/–3 + 14 = 5
⇛ w/–3 = 5 – 14
⇛ w/–3 = – 11
⇛ w = –11 × (–3)
⇛ w = 33
Answer: 1/2x -5
Half of x , less 5. (5 less just means subtract)
